用于无线通信系统中提高通信质量、减小误码率的有效措施的操作工具(Used in wireless communication systems to improve communication quality, effective measures to reduce the error rate)

sunjun编写的量子粒子群算法，MATLAB程序，简单易懂，注释清晰。(QPSO.m coded by Sun Jun, a efficient and effective algorithm, also a Swarm-Intelligent algorithm.)

qc-ldpc码编程，围长为6，列重为3，无4环(The algorithm divides rows into three equal groups. The rows are then connnected to form a distance graph which is then transformed in to a matrix. Girth of six is maintained by avoiding four-cycles. No two rows are connected more than once (the row-column constraint).)

FEM for solving differential equation
